The Philippine Coast Guard said Chinese vessels harassed a supply boat during a resupply mission near Second Thomas Shoal on Saturday, adding to a long series of confrontations in the South China Sea. The shoal, which lies in disputed waters, has become a frequent flashpoint between Manila and Beijing.

According to the Philippine account, the incident took place as the supply vessel moved to support Philippine personnel stationed in the area. The coast guard said Chinese ships acted aggressively near the mission, though details of any damage or injuries were not immediately reported.

Second Thomas Shoal remains one of the most sensitive sites in the maritime dispute. The area has seen repeated face-offs involving coast guard ships, supply runs, and accusations from both governments over unsafe maneuvers and interference at sea.

The latest confrontation underscores how tensions continue to build in the region, where overlapping territorial claims have raised concerns about the risk of miscalculation and wider instability.
